Interesting. It sounds like a really good product.
"3M Novec Engineered Fluids have a number of significant advantages versus other classes of dielectric fluids, including mineral oil. In addition to being non-flammable and non-combustible, Novec fluids have the boiling points and thermal stability needed for two-phase immersion cooling operations. Servicing and maintenance are made easy, since the electronics come out of Novec fluid clean and dry."
